cc; is l: ro ements in Block-Printing Machines, vhich the following is aspeciiication.

{hie ohject of m invention is to construct a. block printing machine forprinting material, such as oil cloth, linoleum, and other which are fedintermittently through a machine and in which there is a series of=cating block carriers which it'ug blocks that make the im pressions asthe material is fed through the machine.

A further ride mean clock on make a object of the invention is to protorautomatically controlling the o that any desired block can ion at time.

er object ol the invention is to con 3t a come for printing borderedrug... or mats and similar iioor or table cow erings.

. 1 mg ma nine, but other forms he used Wi hout depa Irom the es- H13 VI sential e ire oi .ne invention, which is to ically control the clocksso as to allow them to print any predetermined time. Furthermore, Wherethe intention used to i ting rugs having an endless n (3, is a.ransverse sectional View on the border and Where it is desired to makemore than one size of rug, the controlling mechanism is so timed thatany of a series of blocks can be allowed to make the impres-. sion. Inthe present instance, each block or set of blocks prints the full Widthof the machine and eighteen inches in length, and the feeding mechanismfor the material to be printed is so arranged that, said material willmove intermittently for eighteen inches, re maining stationary for asutiicient length of time to allow the block to make the necessaryimpression. Thus I am enabled in one machine to print the bodv of a rug,Where plain centers are duplicated from one to a series of timesaccording to the length of the rug, and to properly print a bordersection eighteen inches wide, in the present instance at each end of thecontemplated rug. The printing blocks are controlled by the automaticmechanism which I will now proceed to describe.

Referring to the drawings, 1 is the frame of the machine consisting ofan upper beam 2 and a lower beam 3. This frame ,is built in the ordinarymanner and on the up or beam 2 are vertical guides 4 for the blockcarriers 5. These ranged to reciprocate vertically in the guides andconsist of vertical slides (5 at each side of the machine and connectingbeams 7 extending from one side of the slide to the other, making therigid construction which is essential in this type of machine.

8, S are the printing blocks, which are detachably secured to thecarriers 5 in the or dinary manner. These blocks may be arranged in setsor in one piece as desired, and can be adjusted so that they will printtrue on the material which is fed intermittently through the machine byendless bands 28 having pins which engage the material.

block carriers are ar-'- 9, 9 are the inking elements having Wheels I 10which travel on rails 11 secured to the frame 1, and these inkingelements are connected together by rods 12 and means are provided forreciprocating the rods longitudinally so that the rollers of the severalinking mechanisms will pass under the blocks 8 and will ink theprojecting surfaces of the blocks. The rollers rotate in the inkfountains, which are made as shown in Figs. 8 and 6.

i3 is a cam shaft, one for each block, and these cam shafts are driveninunison and thereon.

at the same speed in the present instance. At each end of each cam shaftis a cam ll havmg an extension 15, and on the carrier 5 are studs 16 inwhich are mounted rollers 17' which are engaged by the cam, so that, asthe cam rotates, it raises its carrier and the extension 15 insures thereturn of the carrier to the printing position. There'is a long dwell inthe cam so as to hold the carrier in the raised position in order toallow the inking mechanism to pass under the printing blocks and todistribute the ink Projecting from the side of the carrier, in thepresent instance, is a lug 18 with which engages a latch 19 pivoted at20'to the frame.

21 is a pivoted keeper which, when turned by hand, will retain the latchin engage ment with the lug 18, holding that particular block carrierout of action. This is used when it is desired to dispense with the'useof any particular block.

()n the latch 19 is an arm 22 having a weight which causes the latch toautomatically disengage the block carrier. The cam ll has a high portionwhich lifts the carrier above the position of rest so as to al low thelatch to move out of engagement with the lug 18. The latch and the lugare beveled so that when the full weight of the carrier is on the latchit will be held in position and can only be released when the carrier israised.

At each side of the machine,in the present instance, is a series oflatch actuating rods or selectors 24; three rods are shown at each sideand on each of these rodsare collars 25. In the underside of the collarsare screw threaded holes adapted to receive detachable pins 26 which areheld in position by set screwsd ig. 10, or other fastenings, and on eachlatch is a pin 27 which projects under the rods at the collars, so that,if there is a pin on any one collar and that particular rod movesforward, the pin 26 will engage the pin 2? of the latch, forcing it intothe path of the lug 18 on the carrier 5, and as the carrier leaves thehigh part of the cam it will be held by the latch until released againby the return movement of the rod 524. The several rods 24 have theirhearings in b ilCh'GtS on the frame 1.

36 is a cam shaft at one end of the machine, Figs. 4: and 7, and at eachend of this shaft are three cams 37 and on the end of each rodZl is ahead 38 shaped to receive the cam and each head has a roller 39 whichbears against the face of the cam, so that each rod is reciprocatedaccording to the 60- particular cut of the cam. The cams only move therods in one direction in the present instance. A. spring 30 on theopposite end of each rod bears against one of the brackets 35 andmovesthe rod in the opposite direction. An an:-

quired. The same is true when there is only diary spring 31, for thesame purpose, may be used if found necessary, Figs. 2 and 8. The camshaft '36 controlling the rod is driven from one of the main cam shafts13, through a shaft by belting, as shown by dotted lines, Figs. 2, 3 andl. By using the detachable cams 37 and detachable pins :26 the severalcarriers are under control of the cams and their rods and can be movedinto the printing position at any predetermined time.

Referring to Fig. 12, which illustrates in diagram a rug seventy-twoinches long, it will take four impressions to print this rug :1 singlecolor. A single block will make two impressions a; which will have thebody and a portion of the border 3 at each end, while the impressions w,w will be the end portions of therug and will have the end. borders .2and side sections ,7 of the border, and each end will require a separateblock. If there are three colors used in printing this rug, then theseveral portions m of the rug will be printed with a set of threeblocks. one following the other in the order determined upon by theoperator. Then the end 00 of the rug will be printed with three blocksand the opposite end u." will also be printed with three blocks, so thatit will take nine blocks to print a rug of this type haw ing threecolors. If, however, the rugis ninety inches long then there will bethree impressions a: and the same border impressions will be made;Consequently, the same number of blocks, vim, nine, will be reonesect-ion a', so that a threecolored rug of any length desired can beprinted with nine blocks. These blocks, by my improved mechanism, can beautomatically released so as to print at the proper time as the desiredportion of the material comes under the printing block. Thus it will beseen that I provide automatic means for controlling the movement of theprinting blocks. so that any block of a series can be controlled to makean impression at the proper time.

I have shown the invention as mechanically operated through rods andcams, but it will be understood that the latches can be actuated bypneumatic or hydraulic mechanism, using a series of cylinders in whichare plungers, either directly on the latches or indirectly through theabove described rods.
